You haven't. You're demanding to know why HIV research is different than lung cancer research, waiting for someone else to bring it up. Okay, I did.
Huh? Maybe you should instead respond to what I'm actually saying, instead of what you think I'm thinking about saying, but not saying, and waiting for someone else to say. Parsing your comments is giving me a headache. And for the record, I don't know anything about HIV research vs. cancer research, nor what point you're trying to make.
